Porous echo concrete using waste lime stone, and porous echo concrete block unit and connecting pin using the concrete

摘要

The present invention relates to a porous eco-concrete unit block and a porous eco-concrete connecting pin made of porous eco-concrete manufactured by recycling waste limestone that can be assembled and installed on slopes and cuts of embankments and rivers. Waste limestone aggregate crushed to a size of 1438 ~ 1628㎏ / ㎥ and composite new material fiberglass 900 ~ 1000g / ㎥ and slag of 3 ~ 6mm length and added to the cement content within 0.3 ~ 0.5% to general cement cement 290 ~ 330㎏ It is a rectangular parallelepiped made of porous eco concrete manufactured by mixing 70∼110㎏ / ㎥ of water / m 3 and water, and forms “" ”shaped side grooves at the corners and an octagonal central through hole at the center. A porous eco-concrete unit block with an octagonal shape, the upper flat part is narrow and the side flat part is relatively wide, but both sides are symmetrical porous eco concrete connecting pins. One will.
